Description

Technical Field

[0001] This utility model relates to the field of packaging bag processing equipment technology, and in particular to a pressure cutting device for packaging bag production. Background Technology

[0002] Packaging bags are bags used to package various goods, facilitating transportation and storage during production and distribution. They are widely used in daily life and industrial production, not only for their practicality but also, to some extent, reflecting the product's brand image and market positioning. Slitting and die-cutting are key processes in cutting raw packaging bag materials into uniformly sized bags according to design requirements. This process ensures consistent product dimensions, meeting the packaging needs of different products. This requires the use of slitting and die-cutting equipment, as shown below.

[0003] A search revealed patent CN218140237U, which discloses a slitting device for producing environmentally friendly packaging bags. The device includes a base, a slitting table fixed to the top of the base, cleaning rollers on both sides of the slitting table, a slitting blade above the slitting table, and a first electric push rod above the slitting blade. In this invention, the packaging bag passes through the surface of the slitting table. The first electric push rod drives the slitting blade downwards, and a second electric push rod drives a pressing plate downwards, pressing the packaging bag. The slitting blade cuts the packaging bag downwards, keeping it stable. The cut is relatively neat, with high dimensional accuracy, facilitating effective bag cutting. The packaging bag passes between two cleaning rollers, which brush and clean the surface of the bag, removing debris and dust, keeping the bag clean and improving its quality.

[0004] However, the above-mentioned device still has the following areas for optimization. For example, although it can effectively compress the packaging bag before cutting, it requires different electric push rods to control the compression and cutting of the packaging bag separately. This increases the manufacturing cost of the device, and the separate control increases the labor intensity of the workers. At the same time, there is a certain time difference when controlling the two sets of different electric push rods, resulting in poor continuity of action. For example, the compression electric push rod needs to be started first, and the cutting electric push rod needs to be started after the compression is in place, which involves a certain time interval. Therefore, there is an urgent need for a compression and cutting device for packaging bag production to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model discloses a pressure-cutting device for packaging bag production. By setting up a pressure-cutting mechanism, it can automatically complete the continuous action of "pressure plate pressing the packaging bag → cutter following up with cutting" through the linkage structure of "moving plate-spring-pressure plate" during operation, without the need for additional electric push rods or independent control components. Compared with the traditional device design that requires two sets of power sources to control the pressing and cutting separately, it not only effectively reduces the equipment manufacturing cost, but also avoids the action delay problem caused by improper timing control of multiple power sources. The operator does not need to debug two sets of power systems separately, which significantly reduces the complexity of operation and labor intensity. In summary, it solves the problems in the background technology.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model discloses a pressure cutting device for packaging bag production, including a base, a processing table fixedly mounted on the top of the base, an mounting seat vertically fixedly connected to the top of the processing table, an unwinding mechanism mounted at the top of one side of the mounting seat, a pressure cutting seat mounted below the unwinding mechanism on one side of the mounting seat, a cutting groove longitudinally formed on the side of the pressure cutting seat away from the mounting seat, and a material feeding groove formed inside the processing table.

[0008] A pressure cutting mechanism includes a mounting frame and a pressure plate. A fixed plate is fixedly installed inside the mounting frame. A cylinder is fixedly installed through the center of the fixed plate. A movable plate is fixedly connected to the telescopic end of the cylinder. A cutter is fixedly connected to the other side of the movable plate. Two pressure plates are provided. Multiple springs are provided between the pressure plates and the movable plate. The two ends of the springs are fixedly connected to the pressure plates and the movable plate, respectively. The two pressure plates are located above and below the cutter, respectively. The distance between the pressure plates and the pressure cutting seat is smaller than the distance between the cutter and the pressure cutting seat.

[0009] A receiving mechanism, which is located on top of the base.

[0010] Furthermore, the top of the cutting seat is provided with an inclined surface, and the inclined surface of the cutting seat is inclined toward the top of the mounting seat.

[0011] Furthermore, one side of the movable plate is provided with a plurality of first guide rods, which movably pass through the fixed plate. One side of the pressure plate is fixedly connected with a plurality of second guide rods, which movably pass through the movable plate, and the ends of the second guide rods are provided with limiting blocks.

[0012] Furthermore, the fixing plate has multiple through slots, the positions of which match the positions of the second guide rod, and the size of the through slots is larger than the size of the limiting block.

[0013] Furthermore, an anti-slip pad layer is attached and fixed to the side of the pressure plate near the cutting seat, and the anti-slip pad layer is made of rubber material.

[0014] Furthermore, the unwinding mechanism includes a connecting seat, at which an unwinding roller is rotatably mounted, and the unwinding roller is externally connected to a drive motor.

[0015] Furthermore, the receiving mechanism includes an inclined feeding seat and a receiving box. The inclined feeding seat is fixedly installed on the top of the processing table. One side of the inclined feeding seat is attached to the mounting base. The inclined feeding seat is inclined towards the feeding trough and is matched and connected. The receiving box is movably placed on the top of the base. The top of the receiving box has an open design. The receiving box is located below the feeding trough. Handles are provided on both the front and rear sides of the receiving box.

[0016] The present invention has the following advantages over the prior art:

[0017] 1. This technical solution, by setting up a pressure-cutting mechanism, enables the continuous action of "pressure plate pressing the packaging bag → cutter following up with cutting" to be automatically completed through the linkage structure of "moving plate-spring-pressure plate" during operation, without the need for additional electric push rods or independent control components. Compared with the traditional device design that requires two sets of power sources to control the pressing and cutting separately, it not only effectively reduces the equipment manufacturing cost, but also avoids the problem of action delay caused by improper timing control of multiple power sources. The staff does not need to debug two sets of power systems separately, which significantly reduces the complexity of operation and labor intensity, and has high practicality.

[0018] 2. This technical solution incorporates a receiving mechanism, which allows the cut packaging bags to automatically slide into the feeding trough along the inclined direction of the inclined feeding seat under their own gravity during operation. The bags then fall directly into the receiving box below. The entire receiving process requires no manual intervention. Compared to traditional devices that require workers to manually pick up the cut packaging bags, this solution significantly saves receiving time and is particularly suitable for continuous batch production scenarios. It greatly improves the overall efficiency of the production line and has high practicality. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0029] Reference Figures 1-4 A pressure cutting device for packaging bag production includes a base 1, a processing table 2 fixedly mounted on the top of the base 1, an mounting seat 3 vertically fixedly connected to the top of the processing table 2, an unwinding mechanism 4 mounted at the top of one side of the mounting seat 3, a pressure cutting seat 5 mounted below the unwinding mechanism 4 on one side of the mounting seat 3, a cutting groove 6 longitudinally opened on the side of the pressure cutting seat 5 away from the mounting seat 3, and a material feeding groove 7 opened inside the processing table 2.

[0030] The pressure cutting mechanism 8 includes a mounting frame 801 and a pressure plate 802. A fixed plate 803 is fixedly installed inside the mounting frame 801. A cylinder 804 is fixedly installed through the center of the fixed plate 803. A movable plate 805 is fixedly connected to the telescopic end of the cylinder 804. A cutter 807 is fixedly connected to the other side of the movable plate 805. There are two pressure plates 802. Multiple springs 810 are provided between the pressure plates 802 and the movable plate 805. The two ends of the springs 810 are fixedly connected to the pressure plates 802 and the movable plate 805, respectively. The two pressure plates 802 are located above and below the cutter 807, respectively. The distance between the pressure plates 802 and the pressure cutting seat 5 is smaller than the distance between the cutter 807 and the pressure cutting seat 5. The material receiving mechanism 9 is located on the top of the base 1.

[0031] The top of the cutting seat 5 is provided with an inclined surface, which is inclined towards the top of the mounting seat 3; a plurality of first guide rods 806 are provided on one side of the movable plate 805, and the first guide rods 806 movably pass through the fixed plate 803; a plurality of second guide rods 808 are fixedly connected to one side of the pressure plate 802, and the second guide rods 808 movably pass through the movable plate 805, and the end of the second guide rod 808 is provided with a limiting block 809; a plurality of through slots 811 are provided at the fixed plate 803, the position of the through slots 811 matches the position of the second guide rods 808, and the size of the through slots 811 is larger than the size of the limiting block 809; an anti-slip pad layer 812 is attached and fixed to the side of the pressure plate 802 near the cutting seat 5, and the anti-slip pad layer 812 is made of rubber material; the unwinding mechanism 4 includes a connecting seat 401, and an unwinding roller 402 is rotatably installed at the connecting seat 401, and a drive motor 403 is externally connected to the unwinding roller 402.

[0032] In the specific implementation process, during operation, the unwinding mechanism 4 unwinds the packaging bag roll. The end of the packaging bag roll naturally moves downwards under gravity until the bottom of the packaging bag roll moves to a suitable height (i.e., the packaging bag roll moves down to the required size until the distance between its bottom end and the cutter 807 meets the required cutting size of the packaging bag). Then, the cylinder 804 is activated to extend it. The operation of the cylinder 804 drives the movable plate 805 to move, thereby driving the cutter 807 to move. The first guide rod 806 can ensure the overall stability of the movable plate 805. At the same time, it also drives the two pressure plates 802 to move. Since the distance between the pressure plate 802 and the cutting seat is smaller than the distance between the cutter 807 and the cutting seat, the two pressure plates 802 located above and below the cutter 807 will move first. The first step involves contacting the packaging bag and engaging with the pressure-cutting seat 5 to press and fix the packaging bag. As the movable plate 805 continues to move, the spring 810 is compressed, and the second guide rod 808 ensures the overall stability of the pressure plate 802 until the cutter 807 contacts the packaging bag. Engaging with the cutting groove 6 at the pressure-cutting seat 5, the packaging bag can be pressure-cut and slit. Then, the cylinder 804 retracts, driving the cutter 807 and the pressure plate 802 to reset. The cutter 807 separates from the packaging bag first, and the pressure plate 802 then separates from the packaging bag. Repeating the above operation allows the pressure-cutting and slitting of the next packaging bag to begin. Since only one cylinder 804 is needed to complete the pressing, fixing, and slitting of the packaging bag, the continuity and efficiency of the work can be greatly improved.

[0033] The spring 810 between the pressure plate 802 and the movable plate 805 has an elastic buffer function. When the cylinder 804 pushes the movable plate 805 to move, the pressure plate 802 will first contact the packaging bag and achieve a tight fit through the elastic pressure of the spring 810. The rubber anti-slip pad 812 can effectively prevent the packaging bag from shifting during the pressing process. At the same time, the first guide rod 806 accurately guides the movement direction of the movable plate 805, and the second guide rod 808 ensures that the pressure plate 802 always maintains a stable pressure state. This design allows the packaging bag to always be in a stable and fixed state when it is being cut.

[0034] The top of the pressure cutting seat 5 is provided with an inclined surface. The inclined surface of the pressure cutting seat 5 is inclined towards the top of the mounting seat 3 so that the bottom end of the packaging bag roll can enter between the pressure cutting seat 5 and the cutter 807 through the inclined surface of the pressure cutting seat 5 in the initial stage of unwinding.

[0035] The through groove 811 is designed to ensure that the second guide rod 808 can move within a large range and to avoid movement obstruction between the second guide rod 808 and the fixed plate 803.

[0036] Among them, the anti-slip pad 812 can increase the friction between the pressure plate 802 and the packaging bag, thereby improving the pressing and fixing effect of the packaging bag and preventing the packaging bag from sliding and moving.

[0037] The packaging bag roll can be placed on the unwinding roller 402, and the unwinding roller 402 is driven to rotate by the drive motor 403 connected to the unwinding roller 402 to unwind the packaging bag roll.

[0038] The spring 810 can be designed as follows:

[0039] Spring 810 is a cylindrical helical compression spring with an elastic coefficient of 5-8 N / mm, a free length of 30-40 mm, and a wire diameter of 3-5 mm.

[0040] The cutter 807 can be designed as follows:

[0041] The blade angle of the 807 cutter is 20°-30°, and the blade is made of high-speed steel, ensuring that it can quickly cut through packaging bags without wear and tear, and ensuring a clean cut. Specific Implementation Example 2:

[0043] Reference Figure 1 and Figure 5 In a preferred embodiment, the receiving mechanism 9 includes an inclined feeding seat 901 and a receiving box 902. The inclined feeding seat 901 is fixedly installed on the top of the processing table 2. One side of the inclined feeding seat 901 is in contact with the mounting base 3. The inclined feeding seat 901 is inclined towards the feeding groove 7 and matched and connected. The receiving box 902 is movably placed on the top of the base 1. The top of the receiving box 902 is designed with an open type. The receiving box 902 is located below the feeding groove 7. Handles 903 are provided on both the front and rear sides of the receiving box 902.

[0044] In the specific implementation process, when working, the cut packaging bag will automatically slide into the feeding groove 7 along the inclined direction of the inclined feeding seat 901 under its own gravity, and then fall directly into the receiving box 902 below through the feeding groove 7. The entire receiving process does not require manual intervention. Compared with the traditional device that requires staff to manually pick up the cut packaging bag, it can greatly save receiving time and improve work efficiency.

[0045] The receiving box 902 features a top-opening structure, which can accommodate more cut packaging bags and reduce the frequency of material dumping. Meanwhile, the handles 903 on the front and rear sides of the receiving box 902 are ergonomically designed, allowing workers to easily pull the fully loaded receiving box 902 from the base 1 and move it to the next process without bending over or using tools. In addition, the receiving box 902 and the base 1 are movable, allowing for quick replacement of empty boxes according to production needs, avoiding production line stoppages caused by untimely replacement of the receiving box 902, and further ensuring the continuity of the production process.

[0046] The receiving bin 902 can be designed as follows:

[0047] The opening width of the receiving box 902 is 10-15mm larger than the opening width of the discharge trough 7, and the opening length is also 10-15mm larger than the opening length of the discharge trough 7, to ensure that the cut packaging bags can fall completely into the receiving box 902.

[0048] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
